The 3' UTR of Ddx19a and intron 5 of Ddx19b were targeted with two sgRNAs (targeting CTGACAACTGCCAAGAATGGTGG and GGCTCAGAGGTTAAAAGCATGGG) using CRISPR/Cas9 technology, resulting in the deletion of 39,002 bp of sequence including the entire coding region of Ddx19a and the 3' end of Ddx19b. (J:289833)
